A management accountant used to be the person who closed the books, produced the monthly variance report and answered questions about cost. In many Nigerian businesses the same person is now asked to forecast demand, test three pricing scenarios before a board meeting, build a dashboard that shows customer and staff measures, collect energy data for a sustainability disclosure, and say whether a process should be automated.
The work has moved from recording what happened to shaping what happens next. This is the last topic in the course. It explains what management accounting and performance management accounting are, how the role has changed, the skills the new role needs, the main challenges and current issues, and the Nigerian rules that now shape the work.
It draws on the earlier topics on big data and analytics and on social and ethical issues in strategy.
In 30 seconds
Management accounting gives financial and non-financial information to internal users for decisions, planning and control. Its features are: an internal reporting tool, cost analysis for planning and budgeting, tools for performance measurement, and the costing of products and services. Performance management accounting measures, evaluates and improves performance against objectives, using key performance indicators, variance analysis, benchmarking and cost-benefit analysis.
The role is moving from scorekeeper to strategic business partner: working across functions, advising on value creation and leading change. New skills are data analytics, business acumen and continuous learning. The challenges are rapid change, economic volatility, regulation, data security, changing skills, data overload and poor alignment with the organisation. The current issues are digital transformation, alignment of goals, sustainability and ESG reporting, data accuracy and security, and ethics.
In Nigeria, IFRS S1 and S2 reporting becomes mandatory for public interest entities from periods beginning on or after 1 January 2028, and cyber incidents must be reported within 72 hours. Full marks come from linking each change to its effect on the accountant’s work.
From scorekeeper to business partner
Management accounting and performance management accounting
Management accounting, also called managerial accounting, provides financial and non-financial information to internal stakeholders, the managers, to help them decide and plan. It looks inward, unlike financial accounting, which reports outward to investors and others. Its main features are:
- an internal reporting tool for decision-making;
- a focus on cost analysis, which is central to planning and budgeting;
- tools and techniques for performance measurement; and
- the determination of the cost of products and services.
Performance management accounting is the part of management accounting that measures, evaluates and improves the performance of the organisation and of individuals, by comparing results with objectives.
It uses advanced techniques and modern technology to track measures that are both financial (return on capital employed, profit margins, liquidity and solvency measures) and non-financial (output capacity, labour productivity, labour turnover, customer satisfaction, innovation) and links them to corporate goals so that departures from plan are seen and acted on. Its usual tools are key performance indicators, variance analysis, benchmarking and cost-benefit analysis.
The two fields overlap heavily. In practice performance management is the more modern and forward-looking part: it looks at how technology and data are used, how the organisation adapts to change, and how it stays sustainable.
A performance management system sets targets for the main strategic objective and for each strategy, sets consistent targets at every management level, measures actual performance, compares it with the targets, takes control action where appropriate, and changes the targets when it must.
The new role
- Cross-functional collaboration. Management accountants sit in teams with marketing, operations and research, and give real-time insight that shapes decisions as they are made.
- Value creation advisory. They act as trusted advisers: finding new revenue streams, allocating resources, and challenging accepted wisdom to encourage innovation.
- Change management. As organisations go digital, they lead the change and help teams adopt new technology and processes.
- Data visualisation and storytelling. Interactive dashboards give instant sight of the key performance indicators, and the accountant must also tell the story behind the numbers in a way that directors and non-finance managers understand.
- Agility. Static annual budgets give way to rolling forecasts, scenario modelling and continuous performance review, so that strategy keeps pace with the market.
- Global issues. In multinational groups, transfer pricing, currency movements, cultural differences and benchmarking across regions all need accounting input.
- Sustainability. Integrated reporting that joins financial, environmental and social data, careful use of resources and engagement with stakeholders are part of the job.
New skills
The competences have changed:
- data science and analytics and statistical modelling are now essential
- business acumen, including strategic thinking, negotiation and communication, stands alongside technical skill
- continuous learning, through professional development and certification, is needed to keep up with technology and the market
Technology tools that now support the work are big data and analytics, artificial intelligence and automation (which can speed up transaction processing, variance analysis and reporting, and detect anomalies and risks), cloud computing (shared real-time platforms that join financial and non-financial data) and blockchain (tamper-resistant records for transparency and fraud reduction).
Challenges and current issues
Challenges for management accounting
- Rapid change. Globalisation, new competition, and new digital tools, cloud systems and online data storage change how information is obtained and used.
- Economic volatility. Recessions, exchange rate instability and political influence make planning and decisions harder.
- Complex regulation. Accounting standards, tax rules and compliance requirements keep changing and demand more expertise and care.
- Data security and privacy. Management data is open to cyber threats, and cloud storage makes security, confidentiality and integrity more important.
- Changing roles and skills. The accountant must go beyond record-keeping and basic reporting.
- Data overload. Too much data can overwhelm people and systems, and poor data management leads to wrong cost allocation, budgeting errors and inaccurate forecasts.
- Lack of alignment. Practices must fit the organisation’s size, structure, culture, people and management style, and often do not.
Challenges for performance management
- Poorly aligned or unclear goals, which lead to poor motivation and performance.
- Ineffective communication and poor feedback.
- Irrelevant measures, and staff resistance to measures that do not capture what matters.
- Growing volume and complexity of data, which needs analytic tools and advanced systems for accurate, real-time reports.
- Flawed evaluation methods, especially for non-financial data.
- Limited time and resources, and lack of training.
Current issues
- Digital transformation and technology. Automation, better analytics of large data sets, real-time information, cyber security and cloud services. Data must also be stored for future use.
- Alignment of goals. Operational objectives must line up with strategy to avoid dysfunctional behaviour and suboptimisation, where a unit meets its own target at the expense of the whole.
- Sustainability and ESG. Reporting on the environment, social issues and governance, with transparent, accountable reporting.
- Data accuracy and security. Large data sets are prone to error, so accurate processing and protected storage are needed to keep data trustworthy.
- Ethics. Measures must be free from fraud, conflicts of interest and manipulation, and promote honest reporting.
- Talent, governance, taxation and transfer pricing in a global economy, plus continuous improvement through budgeting tools, benchmarking and total quality management.
Modern performance management also stresses employee well-being and engagement, continuous feedback rather than annual appraisal, and the use of newer techniques such as total quality management, customer accounting and throughput accounting.
Nigerian rules that shape the role as at November 2026
- Sustainability reporting. The Financial Reporting Council of Nigeria’s roadmap, amended in 2026, makes IFRS S1 and IFRS S2 mandatory for public interest entities, including all public companies, for periods beginning on or after 1 January 2028, with small and medium-sized entities from 2030. The Securities and Exchange Commission’s circular of 23 September 2026, issued under the Investments and Securities Act 2025, asked public companies to submit adoption plans by 15 October 2026. Management accountants collect and check much of the data, so their systems must be ready a year ahead.
- Personal data. The Nigeria Data Protection Act 2023 applies to personnel, customer and supplier data held in management systems, and a risky breach must be reported to the Commission within 72 hours.
- Cyber incidents. The Cybercrimes (Prohibition, Prevention, etc.) Act 2015, as amended in 2024, requires a cyber threat or incident to be reported to the National Computer Emergency Response Team within 72 hours of detection.

Measuring the finance function and appraising change
- Time saved by automation. Number of staff × loaded annual cost × share of time spent on the task × share of that time saved.
- Net annual benefit and payback. Saving − running cost; set-up cost ÷ net annual benefit. For a multi-year view, NPV = net benefit × annuity factor − set-up cost.
- Break-even saving. Set-up cost ÷ annuity factor = break-even net benefit; add running cost to get the saving needed; divide by the time cost of the task for the share of time that must be saved.
- Forecast error. Error % = |actual − forecast| ÷ actual × 100. The mean of the errors over the periods is the mean absolute percentage error. The lower, the better the forecast.
Money is in ₦ million, percentages are to one decimal place, annuity factors to four decimal places, and each answer is rounded once, at the end.
Worked examples
Example 1: automating month-end reports. Eko Logistics has six accountants who each cost ₦6.0m a year. They spend 35% of their time on manual reporting, and a reporting tool would save 60% of that time. The tool costs ₦12.0m to buy and ₦3.0m a year to run. Required: the annual saving, the net annual benefit and the payback.
- Time cost of the task.
6 × 6.0 × 35% = ₦12.6m. - Annual saving.
12.6 × 60% = ₦7.56m. - Net annual benefit.
7.56 − 3.00 = ₦4.56m. - Payback.
12.0 ÷ 4.56 = 2.63 years. - Comment. The saving is cash only if staff time is redeployed to higher-value work or posts are not refilled, so the plan for released time matters as much as the tool.
Example 2: budget against rolling forecast. A firm’s actual quarterly revenue is ₦120m, ₦135m, ₦150m and ₦140m. The annual budget put ₦130m in each quarter. A rolling forecast, updated each quarter, gave ₦124m, ₦133m, ₦146m and ₦142m. Required: the mean absolute percentage error of each and a conclusion.
- Budget errors.
10 ÷ 120 = 8.3%
5 ÷ 135 = 3.7%
20 ÷ 150 = 13.3%
10 ÷ 140 = 7.1%.
Mean = 8.1%. - Rolling forecast errors.
4 ÷ 120 = 3.3%
2 ÷ 135 = 1.5%
4 ÷ 150 = 2.7%
2 ÷ 140 = 1.4%.
Mean = 2.2%. - Conclusion. The rolling forecast is far more accurate, because it is updated as conditions change. That supports the move from static budgets to continuous forecasting, and it also shows why management accountants must understand data and models.

Information technology in performance management
Designing the system. An IT system can give people enormous amounts of data, with a risk of information overload: users do not know what matters. Design starts with what information each user needs, why, how often, where it comes from, how it will be captured and how it will be reached.
Essential or frequently used items should be provided conveniently (for example the ability to drill down into variances). Items needed rarely can be made accessible and left to the user to find. The system should support the manager’s tasks of setting targets, communicating, organising, co-ordinating, leading, motivating, monitoring and controlling: clear objectives (critical success factors), targets (key performance indicators), actual performance and a comparison with target or forecast.
Executive information systems give senior managers current and historical data with a drill-down facility; decision support systems make sensitivity and scenario testing easy. The risk is excessive detail and control, which can leave staff reporting instead of adding value.
Impact on employer and employee relations. Better communication widens the span of control and flattens hierarchies, since managers can supervise more people and employees can reach senior managers directly by e-mail. Home working cuts accommodation costs, attracts staff and limits disruption, but makes control and co-ordination harder and can leave staff isolated. Groupware lets distant teams work together but teams linked only electronically bond less well.
E-mail speeds work but brings spam, viruses, security risks, time-wasting, hasty replies and careless messages, so use needs control. IT can also cause de-skilling: automated procedures cut training cost but reduce interest in the work and pride in performance.
Challenges in developing an information system. A balance must be struck between meeting user requirements, the quality of design, cost and time. A system of the highest quality cannot usually be built quickly and cheaply. Organisational and social problems, such as resistance from users, are a major cause of failure, so organisational impact analysis should be done early.
It covers the contribution of the system to economic and strategic goals (conformity with the IS/IT strategy, priority for the most important parts, links with business process re-engineering, flexibility for planned change); human issues (training, health and safety, motivation, working styles and skills, job redesign); implementation (timing against other changes, likely disruption); and the effect on structure, culture and the balance of power, since control of information gives power.
The feasibility study. This is the first stage of a project and decides whether a new system is needed and which option is best. A steering committee of senior managers with IT, finance, project and business expertise supervises the project and sets the terms of reference (purpose, scope, budget, timescale); the project sponsor is the champion. Business analysts may have identified the opportunity.
A small feasibility study group (IT experts, user representatives, an accountant) gathers information about the current system, finds its problems, identifies two or three alternatives, tests each and reports.
Each option is tested for technical feasibility (response times, links with other systems, capacity), operational feasibility (staff skills, changes to structure or hours, data conversion, data protection law), social feasibility (likely resistance from employees and customers) and economic feasibility, which uses cost-benefit analysis of the costs and benefits of each option.
Key factors for the success of a new information system
A new information system is more likely to succeed when it has a clear purpose linked to strategy and to the users’ real needs; the visible support of top management and a committed sponsor; the involvement of users in specifying, designing and testing it; a realistic plan, budget and time scale with clear responsibilities; thorough testing and accurate data conversion; adequate training and support for staff; management of the organisational and human effects (resistance, changed jobs); and flexibility for future change, with a review of costs and benefits after implementation.
Failure is usually caused more by organisational and social problems than by the technology.
The role of the management accountant in project management
At initiation, the accountant helps with the feasibility study and the cost-benefit and investment appraisal. During planning, the accountant prepares cost estimates and the project budget, cash flow forecasts and the funding plan, and helps set milestones and targets. During execution and control, the accountant compares actual cost and progress with budget, reports variances and forecast cost to completion, controls change requests and advises on corrective action.
At completion, the accountant carries out the post-completion review of costs against budget and benefits against the case, and records the lessons learned.
More challenges in developing an information system
Other challenges:
- employee resistance to change
- unclear user requirements, so that the system is not aligned with the business
- funding limits
- data security, privacy and legal compliance
- fast technological change, which can make a system out of date soon
- skills gaps that need training
Common mistakes
- Listing technologies without effects. Say what each does to the accountant’s work and what risk it brings.
- Treating management accounting and financial accounting as the same. One serves internal users, the other external.
- Presenting automation as free. It costs money, needs skills and creates security risks.
- Ignoring suboptimisation when discussing goal alignment.
- Forgetting the law. Data protection, cyber reporting and the 2028 sustainability date belong in a current-issues answer.
- No conclusion. Discussion questions need a view.

Model answers
Show the model answer to Question 11
(a) The accountant used to be a scorekeeper who recorded transactions, produced monthly reports and explained past variances (2). The role is now that of a strategic business partner: working in cross-functional teams to give real-time insight, advising on value creation and resource use, and leading change as the organisation digitises (2).
The accountant also uses data and technology to forecast and model scenarios, tells the story behind the numbers, and reports non-financial and sustainability data, so that the role looks forward and outward instead of back and inward (2).
(b) Any four: data analytics and statistical modelling; business acumen; negotiation and communication; technological literacy; continuous learning; ethics and judgement (1 each).
Show the model answer to Question 12
(a)
- Time cost 8 × 5.5 × 30% = 13.2
- saving 13.2 × 65% = ₦8.58m (3).
(b) 8.58 − 3.60 = ₦4.98m (2).
(c) 15.0 ÷ 4.98 = 3.01 years (3).
(d)
- 4.98 × 2.7982 = 13.94
- less 15.00 = −₦1.06m (4).
(e)
- Break-even net benefit 15.0 ÷ 2.7982 = ₦5.36m
- add running cost 3.60 = ₦8.96m a year saving needed
- 8.96 ÷ 13.2 = 67.9% of the time, against 65% expected.
- The project narrowly fails on the measured savings, so it depends on benefits that are harder to measure, such as faster reporting, fewer errors and better decisions, and on the plan for the released time (3).
Show the model answer to Question 13
(a)
- Budget errors.
30 ÷ 220 = 13.6%; 0; 25 ÷ 275 = 9.1%; 5 ÷ 255 = 2.0%. - Mean = 6.2% (5).
(b)
- Rolling forecast errors.
6 ÷ 220 = 2.7% - 4 ÷ 250 = 1.6%
- 5 ÷ 275 = 1.8%
- 3 ÷ 255 = 1.2%.
- Mean = 1.8% (5).
(c) The rolling forecast is much more accurate because it is revised as results come in, whereas the flat budget could not reflect the rising trend. It supports continuous forecasting and better decisions (3).
(d) Any seven points:
- rapid technology change and skills gaps
- cost of systems and the need to justify it
- data overload and poor data quality leading to wrong forecasts
- cyber threats and cloud storage risks
- the duty to report a cyber incident within 72 hours of detection and a personal data breach within 72 hours
- lawful basis, minimisation and cross-border rules under the Nigeria Data Protection Act 2023
- staff resistance to change
- the need for new skills and training
- alignment with the company’s structure and culture
- the 2028 sustainability reporting date for public interest entities (7)
